tailwind-performance

Reduce bundle size by configuring content paths to scan only your project files, enabling JIT mode, and using PurgeCSS to remove unused styles. Tailwind then generates only the CSS classes your code actually uses, dramatically shrinking output.

Set content paths in tailwind.config.js to match your template locations (e.g., './src/**/*.{html,js,jsx,ts,tsx}'). Precise paths ensure Tailwind scans all files containing class names and purges only truly unused CSS.

Avoid string construction for class names; instead, use Tailwind's safelist to explicitly include dynamic classes. This prevents purging from removing classes generated at runtime that static scanning cannot detect.

Tailor build optimization for each framework: enable CSS minification in Tailwind config, use framework-specific tree-shaking, leverage CSS variables, and implement critical CSS extraction and lazy-loading to improve load times across bundlers.

Large CSS usually indicates incorrect content paths (missing or overly broad patterns), dynamic classes not in safelist, or minification disabled. Verify scanning paths match all template files and that all dynamic selectors are explicitly whitelisted.

Yes; Vite, Next.js, and Webpack each handle JIT, code-splitting, and asset optimization differently. Framework-specific configuration ensures content paths are scanned correctly and build strategies align with each tool's bundling approach.
